fix(enrich): add missing user_id field to enriched contact data

enrich_contacts RPC requires user_id in every contact record.
The enrich function was sending enriched data without user_id,
causing 'All records in p_contacts_data must contain user_id field' error.

Also adds enrich function config to supabase/config.toml for
Docker edge runtime registration.
